Question on BADI Macros

Hi All

Facing an issue when using DP BADI macros – The planning book contains 3 key figures. The BADI macro calculates KF3 = KF1 – KF2 (it’s a little more complicated than that..but will do for this discussion). When the BADI macro is manually executed in Interactive Planning (SDP94), it correctly populates KF3 and displays it. But when I try to save the data, the row populated by BADI macro (KF3) disappears.

Strange thing is that if I instead manually enter values in KF3 and save it, its fine.

Does this look like its a problem with the BADI macro coding or is it a SAP bug ? Could not find anything on SDN or OSS. Any help would be appreciated.

Thanks
